Thread: vector of classes

Am getting an error message while trying to create a vector of class objects.

Code:

	std::vector<cannon> cballs;
	cballs.insert(cballs.begin(), new cannon(5*ballNo,90,5));

error C2664: 'class cannon *__thiscall std::vector<class cannon,class std::allocator<class cannon> >::insert(class cannon *,const class cannon &)' : cannot convert parameter 2 from 'class canno
n *' to 'const class cannon &'
Reason: cannot convert from 'class cannon *' to 'const class cannon'
No constructor could take the source type, or constructor overload resolution was ambiguous

From the looks of that error message, it seems you don't need the word 'new'.

Yes, it's the new that's wrong.

Code:

std::vector<cannon> cballs;

You have a vector of cannon objects, but you're using new which is trying to insert cannon* pointers.
